Real Property and Tax Data

The Real Property Lister is responsible for the county’s real property listing and associated assessment functions, supplying parcel-based land information to both land information professionals and to the general public.

Property listing & Tax Information (NOVUS)

NOVUS is the county’s online tax, property, and assessment information database. Use NOVUS to view property listings and tax information.


Tax ID numbers and PIN numbers are two different ID numbers placed on each parcel in the county. Your PIN is a 23 digit number, while tax ID numbers are between 1 and 5 digits. Get a detailed explanation of how these PIN numbers are derived.

Assessment Information

No county in Wisconsin currently operates a County Assessor Office. Property valuation is handled at the local level by municipality.  Find your assessor.

For information on appealing your assessment there is an assessment appeal guide (PDF) from the Wisconsin Department of Revenue. is an external website that hosts some basic assessment information.


After a deed is recorded in the Register of Deeds office, it will move to the office of the Real Property Lister where the ownership and documentation will be updated in NOVUS.


When a parcel is either split or combined with another parcel, the Real Property Lister assigns new Tax ID and PIN number(s), adds in all appropriate ownership, documents, and basic listing information, and then sends to the assessor to add on assessment values. GIS mapping is also updated; please note that updates to the GIS Web Map after NOVUS is updated are not immediate. Please see our guides on each, plus supplementary FAQ and electronic real estate transfer return (eRETR) guides from our Register of Deeds office:

Unsure of property lines?

In addition to reading your deed, a survey is the best way to know your property boundaries. Please note that our GIS Web Map only shows approximate parcel lines and can be up to 200 feet off in some cases. First check if your land has a survey on it - recorded Certified Survey Maps (CSMs) are in the Register of Deeds office, while maps of survey (not recorded) are in the Land Records Department and seen online in our GIS Web Map.  To contact a land surveyor, see the list on our Land Surveying page.
